Positive predictive value versus sensitivity for non-CpG-related promoters. The solid and the long-dashed curves are for CoreBoost, with the solid one for the cases clustering predictions within 2,000 bp and the long-dashed one within 500 bp. The dot-dashed curve is for McPromoter, which clusters predictions within 2,000 bp by default. The dot and the short-dashed curves are for Eponine, with the dot one for the cases clustering predictions within 2,000 bp and the short-dashed one from the default output of Eponine. bp, base pairs.
